Abstract
A great deal of concern has recently arisen regarding the safety of anesthesia in infants and children. Th ere is mounting and convincing preclinical evidence in rodents and non-human primate that anesthetics in common clinical use are neurotoxic to the developing brain in vitro, and cause long-term neurobehavioral abnormalities in vivo . An estimated 6 million children (including 1.5 million infants) undergo surgery and anesthesia each year in the USA alone, so the clinical relevance of anesthetic neurotoxicity is an urgent matter of public health. In this talk, I would like to present our progress and our eff orts in trying to understand how specifi c receptor subunits and intracellular signaling events are involved in anesthetic agent or NMDA antagonist-induced neurotoxicity. Using both in vivo and in vitro experimental models, we are exploring the gene expression profi ling, biochemical and molecular mechanisms that underlie anesthetic-induced oxidative stress, particularly during sensitive developmental stages. I would also discuss how the application of molecular imaging (e.g., microPET) with isotope-labeled biomarkers (radio-tracers) may help to detect neurotoxicity at a suffi cient resolution to resolve both major structures and neuronal activities in the brain of infants, young and adult animals. In addition, the protective roles of some anti-oxidant agents in anesthetic- induced neurotoxicity will be addressed
